Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a welding platform for aluminum alloy profiles. Background Art

[0002] Aluminum alloy is an alloy material based on aluminum and added with a certain amount of other alloying elements. It belongs to light metal materials. It not only has the general properties of aluminum, but also has some specific alloy properties due to the different types and amounts of alloying metals added. Aluminum alloy profiles are industrial materials made of aluminum alloy materials. According to different shapes, they can usually be divided into plates, pipes, and some special-shaped components, etc. During their production and processing, welding equipment is usually required to achieve welding and fixation.

[0003] For example, in the patent document with the patent publication number CN214770069U, a welding platform for special-shaped aluminum alloy parts that can rotate at any angle is disclosed. It includes an operating table, support legs are welded and installed at the bottom of the operating table, an L-shaped support plate is welded and installed at the top of the operating table, an adjustable welding mechanism is arranged below the L-shaped support plate, a box body is welded and installed at the bottom of the operating table, a rotatable mechanism is arranged above the operating table, a fixing mechanism is arranged above the operating table, and a cooling mechanism is arranged on one side of the L-shaped support plate.

[0004] It can be seen from the existing technical literature that this welding platform can drive the turntable through a motor, so that it can achieve rotational motion under the cooperation of the groove on the top of the operating table, thereby facilitating the flexible transposition of the aluminum alloy parts. However, during the welding process, welding slag is likely to enter the gap between the turntable and the groove, and it is difficult to clean up later. After a long time, too much welding slag accumulation is likely to eventually cause the turntable to get stuck. At the same time, this welding platform can finally clamp and fix the aluminum alloy parts through the clamping plate. However, during the welding process, the position of the clamping plate is always fixed relative to the aluminum alloy parts. Therefore, the presence of the clamping plate may cause unnecessary interference to the welding.

[0031] The bottom of the base 1 is fixed to the ground, and its position is fixed. The assembly block 3 can achieve a circumferential rotational movement along the assembly groove 2 through its movable connection with the assembly groove 2.

Driven by the telescopic movement of each vertical electric cylinder 7, the connecting plate 8 moves up and down, and further drives the magnetic adsorption positioning member to move up and down until the top of the magnetic adsorption positioning member finally fits and abuts against the bottom of the welding platform 5.

[0033] When the utility model is working, the operator first places the component to be welded on the top of the welding platform 5, and then controls the end of the telescopic rod of each vertical electric cylinder 7 to extend upward, so that the top of the magnetic adsorption positioning member abuts against the bottom of the welding platform 5. Then, under the action of magnetic adsorption, the component on the top of the welding platform 5 is positioned, and then the welding operation is carried out on it. If the component needs to be rotated and displaced, first, it is necessary to control each vertical electric cylinder 7 to retract to release the adsorption positioning of the welding platform 5 and the aluminum alloy component arranged on its top, and then turn on the driving member, so that the cylinder body 4 and the welding platform 5 can rotate, so as to realize the rotation and displacement of the aluminum alloy component. After the displacement is completed, control the end of the telescopic rod of each vertical electric cylinder 7 to extend again to re-adsorb and position the welding platform 5 and the aluminum alloy component.

[0034] In any of the above solutions, preferably, the magnetic adsorption positioning member includes a horizontally arranged mounting disc 9.

[0035] Place the magnet blocks 13 into the respective mounting grooves 12, and then buckle the buckling cover plate 14 into the buckling groove 11 to realize the blocking of the magnet blocks 13.

[0036] The tops of the mounting disc 9 and the buckling cover plate 14 are flush. When the end of the telescopic rod of the vertical electric cylinder 7 extends upward, their tops jointly abut against the bottom of the welding platform 5. At the same time, under the action of the magnet blocks 13, the aluminum alloy component on the top of the welding platform 5 is magnetically adsorbed and positioned.

[0037] Preferably, in any of the above solutions, the driving member includes a servo motor 15 fixedly arranged, the motor shaft of the servo motor 15 is vertically upward and coaxially fixedly connected with a rotating shaft 16, a gear 17 is coaxially and fixedly sleeved in the middle of the rotating shaft 16, and a gear ring 18 is coaxially and fixedly sleeved at the corresponding position on the circumferential outer surface of the cylinder body 4, and the gear 17 and the gear ring 18 are meshed and connected.

[0038] The servo motor 15 is fixedly arranged through a motor bracket, and at the same time, its motor shaft is coaxially fixedly connected with the rotating shaft 16 through a coupling. The servo motor 15 operates and drives the rotating shaft 16 to rotate, and then drives the gear 17 to rotate. Then, under the meshing connection between the gear 17 and the gear ring 18, the rotational movement of the cylinder body 4 is finally realized.

[0039] Preferably, in any of the above solutions, a limiting inner ring 19 is coaxially arranged in the inner cavity of the cylinder body 4. The circumferential outer wall of the limiting inner ring 19 is close to the circumferential inner wall of the cylinder body 4. The inner side of the bottom of the limiting inner ring 19 is fixedly connected to the inner side of the top of the base 1, and the outer side of the bottom of the limiting inner ring 19 abuts against the inner side of the top of the assembly block 3.

[0040] The limiting inner ring 19 is of an annular structure, the inner diameter of which is equal to the inner diameter of the base 1, and the outer diameter of which is larger than the inner diameter of the assembly block 3. In this way, when the limiting inner ring 19 is coaxially fixed to the top of the base 1, the bottom of its outer side can be pressed against the top of the inner side of the assembly block 3, so as to realize axial limitation of the assembly block 3, ensure that the assembly block 3 can be always stably arranged in the assembly groove 2, and prevent the assembly block 3 from disengaging from the assembly groove 2 during the rotation process.

[0041] Preferably, in any of the above solutions, a limiting outer ring 20 is coaxially arranged outside the cylinder body 4. The circumferential inner wall of the limiting outer ring 20 is close to the circumferential outer wall of the cylinder body 4. The outer side of the bottom of the limiting outer ring 20 is fixedly connected to the outer side of the top of the base 1, and the inner side of the bottom of the limiting outer ring 20 abuts against the outer side of the top of the assembly block 3.

[0042] The limiting outer ring 20 is of an annular structure, the outer diameter of which is equal to the outer diameter of the base 1, and at the same time, the inner diameter of which is smaller than the outer diameter of the assembly block 3. In this way, when the limiting outer ring 20 is coaxially fixed to the base 1, its inner side can realize the pressing connection of the outer side of the assembly block 3, and further realize the axial limitation of the assembly block 3, thereby further improving the stability of the movable connection between the assembly block 3 and the assembly groove 2.

[0043] Preferably, in any of the above solutions, a first ball raceway 21 is coaxially provided on the inner wall of the bottom of the assembly groove 2, and a second ball raceway 22 is coaxially provided at the corresponding position on the bottom of the assembly block 3. A number of balls 23 are also included. The lower parts of the balls 23 are arranged in the first ball raceway 21, and the upper parts of the balls 23 are arranged in the second ball raceway 22.

[0044] The vertical section of the first ball raceway 21 is in the shape of a lower semi-circle, while the vertical section of the second ball raceway 22 is in the shape of an upper semi-circle. When the assembly block 3 is movably installed in the assembly groove 2, the first ball raceway 21 and the second ball raceway 22 together form a complete ball raceway for the balls 23 to roll. By providing a number of balls 23, the friction between the assembly block 3 and the assembly groove 2 can be greatly reduced, thereby improving the smoothness of their relative rotation.

[0045] Preferably, in any of the above solutions, a number of counterbores 24 are spaced apart on the circumferential side of the snap-on cover plate 14, and threaded holes 25 are respectively provided at the corresponding positions on the inner wall of the bottom of the snap-in groove 11. A number of matching bolts 26 are also included, and the bolts 26 are respectively connected to the counterbores 24 and the threaded holes 25 at the corresponding positions.

[0046] The bolt 26 is a hexagon socket head cap screw. Its threaded section passes through the counterbore 24 and is threadedly connected to the threaded hole 25, and at the same time its bolt head presses against the counterbore 24, so that the detachable connection between the snap-on cover plate 14 and the mounting disc 9 is realized, which is convenient for the placement and replacement of the magnet block 13.

[0047] Preferably, in any of the above solutions, a ring-shaped guide plate 27 is also included. The circumferential inner side of the guide plate 27 is coaxially fixed to the circumferential outer side of the welding platform 5, and the circumferential outer side of the guide plate 27 is inclined downward.

[0048] The guide plate 27 has an umbrella-shaped structure. Through the guide plate 27, the movable connection structure between the assembly block 3 and the assembly groove 2, and the meshing connection between the gear 17 and the gear ring 18 can be shielded, so as to prevent welding slag from falling into the gaps of its connection structure, thereby affecting its normal operation.

[0049] Preferably, in any of the above solutions, a wire conduit 28 is fixedly inserted into the installation through hole in the middle of the installation high platform 6.

[0050] The wire conduit 28 penetrates through the installation high platform 6, and at the same time its middle section is buried underground so as to cross from the bottom of the base 1. By threading wires into the wire conduit 28, the power supply to the vertical electric cylinder 7 can be finally realized.

[0051] Specific working principle:

[0052] First, place the aluminum alloy parts to be welded on the welding platform and align the welding positions. Then, drive the mounting disc 9 to move upward through the vertical electric cylinder 7, so that it finally abuts against the bottom of the welding platform 5. Ensure the positioning of the aluminum alloy parts through the magnetic attraction of the magnet block 13, and then perform the welding operation on the aluminum alloy parts through an external welding device. When it is necessary to rotate and displace the aluminum alloy parts, control the vertical electric cylinder 7 to retract, and then turn on the servo motor 15. Thus, through the meshing transmission of the gear 17 and the gear ring 18, and under the movable connection between the assembly block 3 and the assembly groove 2, the cylinder body 4 rotates, and then the welding platform 5 and the aluminum alloy parts rotate and displace. After the position adjustment is completed, control the vertical electric cylinder 7 to extend again, so that the mounting disc 9 abuts against the bottom of the welding platform 5 again, and the adsorption positioning effect on the welding platform 5 and the aluminum alloy parts is realized again.
